DYElNG ANDFINISHING PLUSH FABRICS.

SPECIFICATION forming part of Letters Patent No. 283,500, dated August21, 1883.

. To all whom it may concern Be it known that I, JACOB O. Mncurnn, asubject of the Queen of Great Britain, residing in the town of LittleFalls, county of Passaic, and State of New Jersey, have invented certainnew and useful Improvements in the Manufacture of Nap on Plush Fabrics,fully described and represented in the following specification.

This invention relates generally to the manufacture of all classes ofnap or plush fabrics, but particularly to that class of these fabrics inwhich the threads or yarns composing the body are loosely twisted, sothat along nap or pile can be raised by the process of gigging.

In manufacturing these goods by the processes heretofore employed thefabric, after being woven and fulled in the usual manner, was subjectedto the gigging operation, by which some of the fibers of some of thethreads or yarns composing the clothwere pulled up, so as to raise a napor pile. After the nap was thusraised the fabric was dyed or printed;then steamed to develop and set the color,

and then, while the color. was still in a moist condition, the fabricwas thoroughly washed,

' so as to remove the surplus color, and also all the gumrningingredients of the color, and leave the nap in a soft and pliablecondition. After this it was whipped, dried, and sheared, The nap orpile thus formed was, owing to the loose twisting of the threads oryarns from which it was drawn, left without a firm hold upon the body ofthe fabric, and consequently in such a condition as to be very easilypulled out when brought into contact with other objects. Variousexpedients have beeuadopted to cure this defect, among which is thatdescribed in United States Letters Patent No. 209,805, in which acoating of paste or other adhesive substanceis applied to the back ofthe fabric, so as to be absorbed by the threads or yarns, and thuscement or glue the ends of the fibers forming the nap to the body. Thismethod, while it accomplished to some extent the object sought, entailedan extra operation in the manufacture, and to that extent enhanced thelabor and cost of production.

It is the object of the present invention to obviate this extra laborand expense, and at Application filed July 19, 1883. (A 0 specimens.)

the same time provide means by which the fibers of V the nap shall besecurely held to the body of the fabric.

To that end theinvention consists in a method of manufacture by whichthefibers forming the nap are pasted or glued to or into the threads oryarns in the operation of dyeing or printing, and without the necessityof applying paste or other cement to the back of the fabric.

In carrying the present invention into practice the fabric is woven,fulled, gigged, and dyed or printed in the usual manner, a suitablepaste or cementing substance being, however, mixed with the dye orprinting color, so as to be applied to the nap or face side of thefabric at the same time with the dye or color. This paste or cement maybe formed by simply miXing flour or other like substance with the dye orcolor; but British 1111], or what is known as gum substitute," will befound preferable for the purpose, bccausethese gums, while readilydissolved in hot water, are not readily dissolved in cold water. Afterthe dye or color containing the paste'or cement has been thus appliedthe fabric is submitted to the usual steaming process, by which thecolor is developed or set and the paste or gum thoroughly cooked anddriven into all the interstices of the threads or yarns, so as to holdfast the ends of the fibers forming the nap. The fabric then, instead ofbeing washed while the color is in a moist condition, is allowed tobecome thoroughly dried, so as to set thepaste or gumwhich has soaked orbeen driven into the interstices of the threads or yarns. After beingthus dried it is washed in cold water sufficiently to remove the solubleparts of the paste from the nap, after which it is whipped, dried, andsheared in the usual manner, and is ready for use.

By applying the paste or gum before the steaming, and then allowing thefabric to become thoroughly dried before washing, and then washing incold water, it becomes possible to wash the surplus color andthe solubleparts of the paste or gum from the nap without disturbing that which hasbeen driven into or been absorbed by the threads or yarns of the body,and consequently renders it unneccssaryto apply the paste to the back ofthe p fabric, while by applying the paste or gum in remove the paste orgum from the map, subconnection with the dye or color all necessitystantially as described. of anextra operationforthepurposeis avoided.
